I'm asking because I have a Lifeproof case on my iPhone 6, & the only 2 items that will fit through the case into the headphone hole are the earbuds that came with my phone & the Lifeproof headphone adapter that came with my case. I listen to audiobooks on my phone in the car every day & would like a cable that doesn't require me to use my Lifeproof headphone adapter - which screws into the case to make a water/dust tight seal (which I feel isn't necessary for most car rides). I was on the phone with an Apple Store (outsourced) customer service lady; she informed me that the store in my town does not have this product in stock - I'd have to order online & could have it shipped to that store. I would like to avoid purchasing this item until I know whether or not it will work with my case.
